Title: **Innovative Contributions of Hiroyuki Tomomatsu in Transistor Technology**
Introduction
Hiroyuki Tomomatsu, an accomplished inventor based in Oita, Japan, has made significant strides in the field of transistor technology. With a robust portfolio encompassing 15 patents, Tomomatsu's work is instrumental in advancing electronic device efficiency and performance.
Latest Patents
One of his latest innovations is a transistor device characterized by source field plates and non-overlapping gate runner layers. This groundbreaking design includes a field plate that extends from a source runner layer or a source contact layer, with the potential to be coplanar with or below a gate runner layer. The architecture allows for a gate runner layer that is routed away from the region directly above the gate metal layer using a gate bridge. As a result, the field plate can extend directly above the gate metal layer without interference from the gate runner layer. Placed close to the channel region, this configuration significantly reduces parasitic capacitance. Through the vertical overlap of the metal gate layer and the field plate, his proposed High Electron Mobility Transistor (HEMT) device achieves remarkable size efficiency without the need for additional routings.
